英文摘要 | This study was developed to explore the feasibility of achieving enhanced hydrogen (H-2) and lipid coproduction mediated by H-2-producing microalgae Chlorella protothecoides. C. protothecoides was able to simultaneously produce both H-2 and lipids, and this H-2 and lipid coproduction was found to be inducible under conditions of nitrogen limitation in a closed system. Specifically, optimal H-2 (151.1 mL L-1) and lipid (49.6% DW) coproduction was achieved under 5% N in a closed system. Relative to nitrogen-replete conditions, such nitrogen limitation was able to induce the accumulation of NADPH and reactive oxygen species, thereby directly promoting lipid production. Moreover, in a closed system, these limited nitrogen levels established conditions of anaerobiosis, activating hydrogenase and thereby generating H-2 while suppressing respiratory electron transport, ultimately further augmenting lipid production. Together, these results highlight a novel approach to simultaneously producing H-2 and lipids and to enhancing such coproduction activity. |
